SPEGIFIQATION forming part of Letters Patent No. 694,822, dated March 4, 1902.- Application filed September 5, 1900. Serial lo. 29055. (No model.)

To alli whom t may concern,.-

Beit known that I, ROBERT BINNIE, a citi zen of the United States, and a resident of Bolivar, in the county of VSTestmorelandand State of Pennsylvania, have invented a new and Improved Drill, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide a drill adapted especially for work in coal, clay, and other soft minerals and which will have a drill rod the movement of which adapts it to a bit of any character, eithera boring-tool or a chiseling-tool. B y this means if an ore ball or lump is struck the boring need not be abandoned, as heretofore, but a chiseling-tool may be applied and the work carried on as before. v

This specification is thedisclosure of one form of the invention, While the claims define the actual scope thereof.

Reference is to be had tothe accompanying drawings, forming a part of this specification, in which similar charactersof reference indicate corresponding parts in all the views.

Figure 1 is a front velevation of the invention. Fig. 2 isa view disclosing interior parts and showing the drillin a second position. Fig. 3 is a detail of the feed in side elevation, and Fig. 4 is a det-ail of the feed in top plan.

The drill is carried on posts 5, which support a transverse body-plate 6. One of the posts is adjustable toward and from the othery by means of abolt 7 on the clamp of such post, the bolt working in a slot 10 in the body-plate 6, and this slot also adjustably carries theV bolt 8, which holds the frame-bar 9 of the drilling mechanism.

The working parts of the drill are inclosed in a housing 11, which is preferably made in sections and which has sliding movement on the frame-bar 9, which movement is guided and limited by bolts 12, fitting in a slot in the casing. A feed-screwle is held to turn in the upper end by the guide-'bar 9 and is provided with a handle lfor turning it. This screw passes loosely through two brackets 1G on the casing 11 and is engaged by a feed-nut 17, which is also la pinion and which is held to turn, but not to move, axially in the upper bracket 16. The drill-rod 1S is mounted to slide and to turn in the casing 11 and in the brackets 16 thereof, and a pinion 19, which is Ysplined on the drill-rod, meshes with Vthe nut pinion 17 toV turn the same, and by these means the housing or casing 11 ismoved on the frame-bar 9 to feed vthe drill-rod. The pinion 19 forms part of a worm-wheel 20, these parts being joined by a neck 21, which is arranged to turn in the upper bracketl, and the whole being splined on the drill-shaft. A crank-shaft 22, mounted in boxes 23, carries a worm 24,# Which meshes with the worn-wheel 20, and thereby the worm-wheel is driven, imparting a rotating movement to the drill-shaft- The shaft 22 may carry, if desired, a balancewheel 25 and is driven'from a driveshaft 26, geared with the crank-shaft 22, as shown. To 'the crank of the shaft 22 is attached a ecn- -necting-rod 27, and this rod is joined to a block 28, which slides on the drill-rod. On each side of the block 28 are arranged springs 29, which are tted on the drill-rod and held in place by collars 30 fastened thereto. This vimparts a reciprocal movement to the drillrod, and the springs 29 relieve the drill-rod of the jarring effect of the blow. A spring -31 is placed on the drill-rod below the casing to stop an excessive upward blow. A boringtool is iitted to the drill-,rod in the usual manner, as illustrated in Fig. 2. It will therefore be seen that the drill-rod is driven with a combined rotary and reciprocal movement ,andthat in addition it is gradually fed forA ward to its work. The drill may be adjusted to work in any direction desired and a tool of any sort applied. to the rod. Manual or motive power-,may be employed at Will.

`- Having thus described my invention, I

Yclaim as new and desire to secure by Letters Patent- 1. The combination of a frame-bar, a caseasing or framing, a drill-rod arranged therein and Working With the feed-screw and driven to turn and slide, a rotating drive-shaft with from the Worm-wheel.

1o tating feed-nut held in the casing or framing In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

ROBERT BINNIE.
